72 Charge to tax on sums applied outside the State in repaying certain loans. [FA71 s4(1) to (4) and (6); FA97 s15]

72.—(1) For the purposes of this section—

  • (a) a debt for money loaned shall, to the extent to which that money is applied in or towards satisfying another debt, be deemed to be a debt incurred for satisfying that other debt, and a debt incurred for satisfying in whole or in part a debt within subsection (2)(c) shall itself be treated as within that subsection, and
  • (b) “lender”, in relation to any money loaned, includes any person for the time being entitled to repayment.

  • (3) Where a person ordinarily resident in the State receives in or brings to the State money loaned to such person outside the State, but the debt for that money is wholly or partly satisfied before such person does so, subsection (2) shall apply as if the money had been received in or brought to the State before the debt was so satisfied, except that any sums treated by virtue of that subsection as received in the State shall be treated as so received at the time when the money so loaned is actually received in or brought to the State.
  • (4) Where a person is indebted for money loaned to him or her, income applied by the person in such a way that the money or property representing the income is held by the lender on behalf of or to the account of the person in such circumstances as to be available to the lender for the purpose of satisfying or reducing the debt by set-off or otherwise shall be treated as applied by the person in or towards its satisfaction if, under any arrangement between the person and the lender, the amount for the time being of the person's indebtedness to the lender, or the time at which it is to be repaid in whole or in part, depends in any respect directly or indirectly on the amount or value so held by the lender.
  • (5) In relation to income applied in or towards satisfaction of a debt for money loaned on or after the 20th day of February, 1997, or a debt incurred for satisfying in whole or in part any such debt, this section shall apply as if the references to ordinarily resident in the State in subsections (2) and (3) were references to resident or ordinarily resident in the State.

73.—(1) In this section, “rents” includes any payment in the nature of a royalty and any annual or periodical payment in the nature of a rent derived from any lands, tenements or hereditaments, including lands, tenements and hereditaments to which section 56 would apply or would have applied if such lands, tenements and hereditaments were situate in the State.

  • (a) Income tax in respect of income arising from possessions in Great Britain or Northern Ireland, other than stocks, shares, rents or the occupation of land, shall be computed either—
  • (i) on the full amount of such income arising in the year of assessment, or
  • (ii) on the full amount of such income on an average of such period as the case may require and as may be directed by the Appeal Commissioners,

so that according to the nature of the income the tax may be computed on the same basis as that on which it would have been computed if the income had arisen in the State, and subject in either case to a deduction on account of any annuity or other annual payment (apart from annual interest) payable out of the income to a person not resident in the State, and the provisions of the Income Tax Acts (including those relating to the delivery of statements) shall apply accordingly.

  • (b) The person chargeable and assessable in accordance with paragraph (a) shall be entitled to the same allowances, deductions and reliefs as if the income had arisen in the State.

74 Case IV: basis of assessment. [ITA67 s79; FA96 s132(1) and Sch5 PtI par1 (2)]

75.—(1) Without prejudice to any other provision of the Income Tax Acts, the profits or gains arising from—

  • (a) any rent in respect of any premises, and
  • (b) any receipts in respect of any easement,

shall, subject to and in accordance with the provisions of the Income Tax Acts, be deemed for the purposes of those Acts to be annual profits or gains within Schedule D, and the person entitled to such profits or gains shall be chargeable in respect of such profits or gains under Case V of that Schedule; but such rent or such receipts shall not include any payments to which section 104 applies.

  • (2) Profits or gains chargeable under Case V of Schedule D shall, for the purposes of ascertaining liability to income tax, be deemed to issue from a single source, and subsection (3) shall apply accordingly.
  • (3) Tax under Case V of Schedule D shall be computed on the full amount of the profits or gains arising within the year of assessment.
  • (4) Neither this section nor section 97 or 384 shall apply to a case in which the rent reserved under a lease (including, in the case of a lease granted on or after the 6th day of April, 1963, the duration of which does not exceed 50 years, an appropriate sum in respect of any premium payable under the lease) is insufficient, taking one year with another, to defray the cost to the lessor of fulfilling such lessor's obligations under the lease and of meeting any expense of maintenance, repairs, insurance and management of the premises subject to the lease which falls to be borne by such lessor.
  • (5) Section 96 shall apply for the interpretation of this section as it applies for the interpretation of Chapter 8 of this Part.

CHAPTER 5 Computational provisions: corporation tax

76 Computation of income: application of income tax principles. [CTA76 s11(1), (2)(b) and (3) to (8); FA96 s132(2) and Sch5 PtII]

76.—(1) Except where otherwise provided by the Tax Acts, the amount of any income shall for the purposes of corporation tax be computed in accordance with income tax principles, all questions as to the amounts which are or are not to be taken into account as income, or in computing income, or charged to tax as a person's income, or as to the time when any such amount is to be treated as arising, being determined in accordance with income tax law and practice as if accounting periods were years of assessment.

  • (2) For the purposes of this section, “income tax law”, in relation to any accounting period, means the law applying to the charge on individuals of income tax for the year of assessment in which that accounting period ends, but does not include such of the enactments of the Income Tax Acts so applying as make special provision for individuals in relation to matters referred to in subsection (1).
  • (3) Accordingly, for the purposes of corporation tax, income shall be computed and the assessment shall be made under the like Schedules and Cases as apply for the purposes of income tax, and in accordance with the provisions applicable to those Schedules and Cases, but (subject to the Corporation Tax Acts) the amounts so computed for several sources of income, if more than one, together with any amounts to be included in respect of chargeable gains, shall be aggregated to arrive at the total profits.
  • (4) Nothing in this section shall be taken to mean that income arising in any period is to be computed by reference to any other period (except in so far as this results from apportioning to different parts of a period income of the whole period).
  • (5) Subject to section 77 and to any enactment applied by this section which expressly authorises such a deduction, no deduction shall be made for the purposes of the Corporation Tax Acts in computing income from any source—
  • (a) in respect of dividends or other distributions, or
  • (b) in respect of any yearly interest, annuity or other annual payment or any other payments mentioned in section 104 or 237(2), but not including sums which are, or but for any exemption would be, chargeable under Case V of Schedule D.
  • (6) Without prejudice to the generality of subsection (1), any provision of the Income Tax Acts, or of any other statute, which confers an exemption from income tax, provides for the disregarding of a loss, or provides for a person to be charged to income tax on any amount (whether expressed to be income or not, and whether an actual amount or not), shall, except where otherwise provided, have the like effect for the purposes of corporation tax.
  • (7) This section shall not have effect so as to apply for the purposes of corporation tax anything in section 71.
  • (8) Where by virtue of this section or otherwise any enactment applies both to income tax and to corporation tax—
  • (a) that enactment shall not be affected in its operation by the fact that income tax and corporation tax are distinct taxes but, in so far as is consistent with the Corporation Tax Acts, shall apply in relation to income tax and corporation tax as if they were one tax, so that, in particular, a matter which in a case involving 2 individuals is relevant for both of them in relation to income tax shall in a like case involving an individual and a company be relevant for such individual in relation to income tax and for such company in relation to corporation tax, and
  • (b) for that purpose, references in any such enactment to a relief from or charge to income tax or to a specified provision of the Income Tax Acts shall, in the absence of or subject to any express adaptation, be construed as being or including a reference to any corresponding relief from or charge to corporation tax or to any corresponding provision of the Corporation Tax Acts.

77 Miscellaneous special rules for computation of income. [CTA76 s12(1) to (7)]

77.—(1) For the purposes of corporation tax, income tax law as applied by section 76 shall apply subject to subsections (2) to (7).

  • (2)
  • (a) Where a company begins or ceases to carry on a trade, or to be within the charge to corporation tax in respect of a trade, the company's income shall be computed as if that were the commencement or, as the case may be, discontinuance of the trade, whether or not the trade is in fact commenced or discontinued.
  • (b) Notwithstanding paragraph (a), where any provision of the Income Tax Acts is applied for corporation tax by the Corporation Tax Acts, this subsection shall not apply for any purpose of that provision if under any enactment a trade is not to be treated as permanently discontinued for the corresponding income tax purpose.
  • (3) In computing income from a trade, section 76(5)(b) shall not prevent the deduction of yearly interest.
  • (4) In computing a company's income for any accounting period from the letting of rights to work minerals in the State, there may be deducted any sums disbursed by the company wholly, exclusively and necessarily as expenses of management or supervision of those minerals in that period; but any enactments restricting the relief from income tax that might be given under section 111 shall apply to restrict in the like manner the deductions that may be made under this subsection.
  • (5) Where a company is chargeable to corporation tax in respect of a trade under Case III of Schedule D, the income from the trade shall be computed in accordance with the provisions applicable to Case I of Schedule D.
  • (6) The amount of any income arising from securities and possessions in any place outside the State shall be treated as reduced (where such a deduction cannot be made under, and is not forbidden by, any provision of the Income Tax Acts applied by the Corporation Tax Acts) by any sum paid in respect of income tax in the place where the income has arisen.
  • (7) Paragraphs (e) and (f) of Case III of Schedule D in section 18(2) shall for the purposes of corporation tax extend to companies not resident in the State, in so far as those companies are chargeable to tax on income of descriptions which, in the case of companies resident in the State, are within those paragraphs (but without prejudice to any provision of the Income Tax Acts specially exempting non-residents from income tax on any particular description of income).

78 Computation of companies' chargeable gains. [CTA76 s13(1), (1A), (1B), (1C), (2), (3)(a) and (c), (4) and (5); FA82 s31(1); FA88 Sch3 PtI par1(b); FA97 s59(2) and Sch6 PtI par1]

78.—(1) Subject to this section, the amount to be included in respect of chargeable gains in a company's total profits for any accounting period shall be determined in accordance with subsection (3) after taking into account subsection (2).

  • (2) Where for an accounting period chargeable gains accrue to a company, an amount of capital gains tax shall be calculated as if, notwithstanding any provision to the contrary in the Corporation Tax Acts, capital gains tax were to be charged on the company in respect of those gains in accordance with the Capital Gains Tax Acts, and as if accounting periods were years of assessment; but, in calculating the amount of capital gains tax, section 31 shall apply as if the reference in that section to deducting allowable losses were a reference to deducting relevant allowable losses.
  • (3)
  • (a) The amount referred to in subsection (1) shall be an amount which, if (before making any deduction from the amount) it were charged to corporation tax as profits of the company arising in the accounting period at the rate specified in section 21(1), would produce an amount of corporation tax equal to the amount of capital gains tax calculated for that accounting period in accordance with subsection (2).
  • (b) For the purposes of paragraph (a), where part of the accounting period falls in one financial year (in this paragraph referred to as the “first-mentioned financial year”) and the other part falls in the financial year succeeding the first-mentioned financial year and different rates are in force under section 21(1) for each of those years, “the rate specified in section 21(1)” shall be deemed to be a rate per cent determined by the formula—
(A × C) ______ E + (B × D) ______ E

where—

A is the rate per cent in force for the first-mentioned financial year,

B is the rate per cent in force for the financial year succeeding the first-mentioned financial year,

C is the length of that part of the accounting period falling in the first-mentioned financial year,

D is the length of that part of the accounting period falling in the financial year succeeding the first-mentioned financial year, and

E is the length of the accounting period.

  • (c) Paragraph (b) shall apply as respects accounting periods ending on or after the 1st day of April, 1997, as if—
  • (i) the period beginning on the 1st day of January, 1996, and ending on the 31st day of March, 1997, and
  • (ii) the period beginning on the 1st day of April, 1997, and ending on the 31st day of December, 1998,

were each a financial year.

  • (4) In subsection (2)—

“chargeable gains” does not include chargeable gains accruing on relevant disposals within the meaning of section 648;

“relevant allowable losses” means any allowable losses accruing to the company in the accounting period and any allowable losses previously accruing to the company while it has been within the charge to corporation tax in so far as they have not been allowed as a deduction from chargeable gains accruing in any previous accounting period.

  • (5) Except where otherwise provided by the Corporation Tax Acts, chargeable gains and allowable losses shall for the purposes of corporation tax be computed in accordance with the principles applying for capital gains tax, all questions as to the amounts which are or are not to be taken into account as chargeable gains or as allowable losses, or in computing gains or losses, or charged to tax as a person's gain, or as to the time when any such amount is to be treated as accruing, being determined in accordance with the provisions relating to capital gains tax as if accounting periods were years of assessment.
  • (6) Subject to subsection (8), where the enactments relating to capital gains tax contain any reference to income tax or to the Income Tax Acts, the reference shall, in relation to a company, be construed as a reference to corporation tax or to the Corporation Tax Acts; but—
  • (a) this subsection shall not affect the references to income tax in section 554(2), and
  • (b) in so far as those enactments operate by reference to matters of any specified description, for corporation tax account shall be taken of matters of that description which are confined to companies, but not of any such matters which are confined to individuals.
  • (7) The Capital Gains Tax Acts as extended by this section shall not be affected in their operation by the fact that capital gains tax and corporation tax are distinct taxes but, in so far as is consistent with the Corporation Tax Acts, shall apply in relation to capital gains tax and corporation tax on chargeable gains as if they were one tax, so that, in particular, a matter which in a case involving 2 individuals is relevant for both of them in relation to capital gains tax shall in a like case involving an individual and a company be relevant for such individual in relation to capital gains tax and for such company in relation to corporation tax.
  • (8) Where assets of a company are vested in a liquidator, this section and the enactments applied by this section shall apply as if the assets were vested in, and the acts of the liquidator in relation to the assets were the acts of, the company (acquisitions from or disposals to the liquidator by the company being disregarded accordingly).

which, in the opinion of the auditor appointed under section 160 of the Companies Act, 1963, or under the law of the State in which the resident company or non-resident company, as the case may be, is incorporated and which corresponds to that section, presents a true and fair view of the profit or loss of the resident company or the business of the non-resident company, as the case may be;

  • (b) The treatment of a contract entered into by a company as a relevant contract for the purposes of this section shall be disregarded for any other purpose of the Tax Acts.

  • (i) a relevant contract of the company, or
  • (ii) money held by the company for the purposes of a trade carried on by it,

so much of that gain or loss as results directly from a change in a rate of exchange shall not be a chargeable gain or an allowable loss, as the case may be, of the company.

shall not be a chargeable gain or an allowable loss, as the case may be, of the company.

89 Valuation of trading stock at discontinuance of trade. [ITA67 s62(1) (apart from proviso) and (2); FA70 s23(4)]

89.—(1) (a) In this section, “trading stock” means, subject to paragraph (b), property of any description, whether real or personal, which is either—

  • (i) property such as is sold in the ordinary course of the trade in relation to which the expression is used or would be so sold if it were mature or if its manufacture, preparation or construction were complete, or
  • (ii) materials such as are used in the manufacture, preparation or construction of property such as is sold in the ordinary course of that trade.
  • (b) For the purposes of this section, “trading stock”, in relation to a trade, includes any services, article or material which, if the trade were a profession, would be treated as work in progress of the profession for the purposes of section 90, and references to the sale or transfer of trading stock shall be construed accordingly.
  • (c) References in this section to a trade having been discontinued or to the discontinuance of a trade shall be construed as not referring to or including any case where such trade was carried on by a single individual and is discontinued by reason of such individual's death (whether such trade is or is not continued by another person after such death), but shall be construed as referring to and including every other case where a trade has been discontinued or is, by virtue of any of the provisions of the Tax Acts, treated as having been discontinued for the purpose of computing tax.
  • (2) In computing the profits or gains of a trade which has been discontinued, any trading stock belonging to the trade at the discontinuance of the trade shall be valued in accordance with the following provisions:
  • (a) in the case of any such trading stock—
  • (i) which is sold, or is transferred for valuable consideration, to a person who carries on or intends to carry on a trade in the State, and
  • (ii) the cost of which to such person on such sale or transfer may be deducted by such person as an expense in computing for any purpose of the Tax Acts the profits or gains of the trade carried on or intended to be carried on by such person,

the value of such trading stock shall be taken to be the price paid for such trading stock on such sale or the value of the consideration given for such trading stock on such transfer, as the case may be;

  • (b) in the case of any other such trading stock, the value of such other trading stock shall be taken to be the amount which it would have realised if it had been sold in the open market at the discontinuance of the trade.

90 Valuation of work in progress at discontinuance of profession. [FA70 s23(1) to (3) and (5); FA81 s9(d)]

  • (a) if the work is transferred for money or any other valuable consideration to a person who carries on or intends to carry on a profession in the State, and the cost of the work may be deducted by that person as an expense in computing for any such purpose the profits or gains of that profession, the value of the work shall be taken to be the amount paid or other consideration given for the transfer;
  • (b) if the work is not to be valued under paragraph (a), its value shall be taken to be the amount which would have been paid for a transfer of the work on the date of the discontinuance as between parties at arm's length.
  • (2) Where a profession is discontinued and the person by whom it was carried on immediately before the discontinuance so elects, by notice in writing sent to the inspector at any time within 24 months after the discontinuance, the amount, if any, by which the value of the work in progress at the discontinuance (as ascertained under subsection (1)) exceeds the actual cost of the work shall not be taken into account in computing the profits or gains of the period immediately before the discontinuance, but the amount by which any sums received for the transfer of the work exceed the actual cost of the work shall be included in the sums chargeable to tax under section 91 as if it were a sum to which that section applies received after the discontinuance.
  • (3) Subsections (1) and (2) shall apply where a profession is treated for any of the purposes of the Tax Acts as permanently discontinued as they apply in the case of an actual discontinuance, but shall not apply in a case where a profession carried on by a single individual is discontinued by reason of such individual's death.
  • (4) References in this section to work in progress at the discontinuance of a profession shall be construed as references to—
  • (a) any services performed in the ordinary course of the profession, the performance of which was wholly or partly completed at the time of the discontinuance and for which it would be reasonable to expect that a charge would have been made on their completion if the profession had not been discontinued, and
  • (b) any article produced, and any such material as is used, in the performance of any such services,

and references in this section to the transfer of work in progress shall include references to the transfer of any benefits and rights which accrue, or might reasonably be expected to accrue, from the carrying out of the work.

91 Receipts accruing after discontinuance of trade or profession. [FA70 s20(1) to (4) and (5)(b), (c) and (d)]

91.—(1) Subject to subsection (2), this section shall apply to all sums arising from the carrying on of a trade or profession during any period before the discontinuance of the trade or profession (not being sums otherwise chargeable to tax), in so far as the amount or value of the sums was not taken into account in computing the profits or gains for any period before the discontinuance, and whether or not the profits or gains for the period were computed on an earnings basis or on a conventional basis.

  • (2) This section shall not apply to any of the following sums—
  • (a) sums received by a person beneficially entitled to such sums who is not resident in the State, or by a person acting on such person's behalf, which represent income arising directly or indirectly from a country or territory outside the State,
  • (b) a lump sum paid to the personal representatives of the author of a literary, dramatic, musical or artistic work as a consideration for the assignment by them, wholly or partially, of the copyright in the work,

  • (d) sums arising to an individual from a work which is such that any profits or gains that might have arisen to the individual from its publication, production or sale, as the case might be, would in accordance with section 195(3) have been disregarded for the purposes of the Income Tax Acts if they had arisen before the discontinuance of that individual's profession.
  • (3) Where any trade or profession, the profits or gains of which are chargeable to tax under Case I or II of Schedule D, has been permanently discontinued, tax shall be charged under Case IV of that Schedule in respect of any sums to which this section applies received after the discontinuance subject to any such deduction as is authorised by subsection (4).
  • (4) In computing the charge to tax in respect of sums received by any person which are chargeable to tax by virtue of this section (including amounts treated as sums received by such person by virtue of section 87), there shall be deducted from the amount which apart from this subsection would be chargeable to tax—
  • (a) any loss, expense or debit (not being a loss, expense or debit arising directly or indirectly from the discontinuance itself) which, if the trade or profession had not been discontinued, would have been deducted in computing for tax purposes the profits or gains of the person by whom the trade or profession was carried on before the discontinuance, or would have been deducted from or set off against those profits or gains as so computed, and
  • (b) any capital allowance to which the person who carried on the trade or profession was entitled immediately before the discontinuance and to which effect has not been given by means of relief before the discontinuance.
  • (5) For the purposes of this Chapter—
  • (a) the profits or gains of a trade or profession in any period shall be treated as computed by reference to earnings where all credits and liabilities accruing during that period as a consequence of the carrying on of the trade or profession are taken into account in computing those profits or gains for tax purposes, and not otherwise, and “earnings basis” shall be construed accordingly,
  • (b) the profits or gains of a trade or profession in any period shall be treated as computed on a conventional basis where they are computed otherwise than by reference to earnings, and
  • (c) the value of any sum received in payment of a debt shall be treated as not taken into account in the computation to the extent that a deduction has been allowed in respect of that sum under section 81(2)(i).

92 Receipts and losses accruing after change treated as discontinuance. [FA70 s22]

92.—(1) This section shall apply in any case where, as a result of a change in the persons engaged in carrying on a trade or profession, the trade or profession is treated for any of the purposes of the Tax Acts as if it had been permanently discontinued and a new trade or profession set up and commenced.

  • (2)
  • (a) Sections 91 and 95 shall apply in the case of any such change as if the trade or profession had been permanently discontinued.
  • (b) Notwithstanding paragraph (a), where the right to receive any sums to which section 91 applies is or was transferred at the time of the change to the persons carrying on the trade or profession after the change, tax shall not be charged by virtue of that section, but any sums received by those persons by virtue of the transfer shall be treated for all purposes as receipts to be taken into the computation of profits or gains of the trade or profession in the period in which they are received.
  • (3) In computing for tax purposes the profits or gains of the trade or profession in any period after the change, there may be deducted a sum equal to any amount proved during that period to be irrecoverable in respect of any debts credited in computing for tax purposes the profits or gains for any period before the change (being debts the benefit of which was assigned to the persons carrying on the trade or profession after the change), in so far as the total amount proved to be irrecoverable in respect of those debts exceeds any deduction allowed in respect of them under section 81(2)(i) in a computation for any period before the change.

93 Cash basis, etc: relief for certain individuals. [FA70 s25]

93.—(1) In this section—

“the net amount” with which a person is chargeable to tax under section 91 means the amount with which such person is so chargeable after making any deduction authorised by section 91(4) but before giving any relief under this section;

“relevant date” means—

  • (a) in relation to tax under section 91, the date of the permanent discontinuance, and
  • (b) in relation to tax under section 94, the date of the change of basis.
  • (2) Where an individual born before the 6th day of April, 1919, or the personal representative of such an individual, is chargeable to tax under section 91 or 94 and—
  • (a) the individual was engaged in carrying on the trade or profession on the 4th day of August, 1970, and
  • (b) the profits or gains of the trade or profession were not computed by reference to earnings in the period in which the date specified in paragraph (a) fell, or in any subsequent period ending before or on the relevant date,

the net amount with which such individual is so chargeable to tax shall be reduced by multiplying that net amount by the fraction specified in subsection (4).

  • (3) Where section 94 applies in relation to a change of basis taking place on a date before the 4th day of August, 1970, then, in relation to tax chargeable by reference to that change of basis, subsection (2) shall apply as if—
  • (a) that earlier date were substituted for the date specified in paragraph (a) of that subsection, and
  • (b) paragraph (b) of that subsection were deleted.
  • (4) The fraction referred to in subsection (2) is—
  • (a) where on the 6th day of April, 1970, the individual had not attained the age of 52 years, nineteen-twentieths,
  • (b) where on that date the individual had attained the age of 52 years, but had not attained the age of 53 years, eighteen-twentieths, and so on, reducing the fraction by one-twentieth for each year the individual had attained, up to the age of 64 years,
  • (c) where on that date the individual had attained the age of 65 years or any greater age, five-twentieths.

94 Conventional basis: general charge on receipts after change of basis. [FA70 s26(1) to (4)]

94.—(1) Where in the case of any trade or profession the profits or gains of which are chargeable to tax under Case I or II of Schedule D there has been—

  • (a) a change from a conventional basis to the earnings basis, or
  • (b) a change of conventional basis which may result in receipts dropping out of computation,

tax shall be charged under Case IV of Schedule D in respect of sums to which this subsection applies which are received after the change and before the trade or profession is permanently discontinued.

  • (2) Subsection (1) shall apply to all sums arising from the carrying on of the trade or profession during any period before the change (not being sums otherwise chargeable to tax) in so far as their amount or value was not taken into account in computing the profits or gains for any period.
  • (3) Where in the case of any profession the profits or gains of which are chargeable to tax under Case II of Schedule D—
  • (a) there has been a change from a conventional basis to the earnings basis, or a change of conventional basis, and
  • (b) the value of work in progress at the time of the change was debited in the accounts and allowed as a deduction in computing profits for tax purposes for a period after the change,

then, in so far as no counterbalancing credit was taken into account in computing profits for tax purposes for any period ending before or on the date of the change, tax shall be charged under subsection (1) in respect of that amount for the year of assessment in which the change occurred as if that amount were a sum to which subsection (2) applies and the change of basis were a change of the kind described in subsection (1).

  • (4) In this section, references to work in progress at the time of a change of basis shall be construed in accordance with section 90(4) but as if references in that section to the change of basis were references to the discontinuance.
  • (5) There shall be a change from a conventional basis to the earnings basis at the end of a period, the profits or gains of which were computed on a conventional basis, if the profits or gains of the next succeeding period are computed by reference to earnings and, if the profits or gains of 2 successive periods are computed on different conventional bases, a change of conventional basis shall occur at the end of the earlier period.
